You realize the data is scarce because the phenomena hasn't been studied, right? You seem to be hung up on the Sister-Wives nonsense and see it as the only viable data point in a truly unanalyzed section of human behavior. The fact of the matter is that I personally know people who are polyarmous and none of them are the creepy Mormon/Branch-Davidian type. Most that I know who are poly are queer (like myself) and far from religious.

If anything, it should be you that should go and create a research program analyzing the nature of poly relationships in humans and the underlying causes, not me. I merely pointed out the reality that our law should consider accommodation for those individuals as it does for others. All you seem to be bringing to the table is scare mongering that depends more on the tiniest of slivers of human society for the proposition that poly relationships should be illegal. Such a proposition is not tenable on it's face nor in its contents thus far. Or in simpler terms: please do your own research because I'm not here to convince you either way (but you seem damn sure to convince me that my poly friends are some evil bad fundies wanting to rape children).

Edit: sorry for the rudeness. I take things personally sometimes.
